Viagra or generic Viagra: How It Works?
Viagra or generic Viagra works in essentially the same way to Levitra and Cialis and all three are called phosphodiesterase 5 inhibitors (PDE 5). In smooth muscle cells, cyclic guanosine monophosphate (cGMP), mediates smooth muscle relaxation.
The more cGMP in your bloodstream, the more the muscles can relax and more blood can flow into your penis to give you a better the erection. PDE 5 breaks down cGMP, so PDE 5 inhibitors like Viagra or generic Viagra keep this from happening, helping to maintain high levels of cGMP.
Viagra or generic Viagra is available in 25 mg, 50 mg and 100 mg pills and can treat a cause of erectile dysfunction such as vascular problems. We advise cutting a 50 mg pill in half and trying 25 mg first, see how it works, then increase the dose by 25 mg if required. People over the age of 65 or people taking certain prescription medications might consider taking a lower dose.
